ZCO and Terminal Services

Have a real PIA issue at the moment We are running a Win2K TS server with Outlook installed. Outlook connects okay to Zimbra and syncronises just fine. The issue comes when our client attempts to use Adobe Standard and the Attach Mail feature. The Outlook send mail dialogue box comes up, they fill in the recipient address, and then click send. The Outlook icon appears in the systray and the email arrives in the recipient Inbox. Though if they then try and attach the email again Adobe is throwing a "Memory cannot be read error". I have ran ProcMon (SysInternals) against it and when that error happens the only issue I can see before the exception is the following

Log files. Enable ZCO logging (just logging and HTTP logging), and repro the problem again. There may also be a log file in the same directory for the Adobe process as well. If that exists, send that as well.
